Visus Next Generation Neon And Signage Lights
VISUS PHOTONICS offers large core UHB High Performance Fiber Optic Lighting Systems with unique DOPITM modular LED & CCFL Light Engine, that out-perform the conventional devices and offer an unparalleled flexibility to meet different application needs needs. Our HOWTM fiber lighting system is fundamentally different from all conventional systems in all three core system components: � � � Multiple DOPITM Miniature Light Engines coupled to a side face of light fiber of any length. No need for a massive conventional edge-coupled Light Engine restricting fiber length and causing high flux losses.

Visus Next Generation Neon And Signage Lights
Visus Next Generation Neon Light requires less than 2 Watt per one meter. How: 95% of LED light gets used in the Visus Next Generation Neon and Signage Li ht as opposed to f li ht t d i th Vi N tG ti N d Si Lights, dt 20% in most current Neon and LED Lights. Advantages: 1. 2. 3. 4. 4 5. 6. 7. 8. 8 9. 90% -99% electricity savings. Longer lifetime (50,000 to 100,000 hours vs. 20,000 hours for Neon). Safety - no high voltages, no transformers. Patented P t t d HOWTM allows coupling high brightness LEDS into thin fibers ll li hi h b i ht i t thi fib Improved LED cooling. Directionality of illumination focuses light only where it is needed, saving 50-75% of light output. Higher spectral Gamut. No harmful mercury (R h compliant) N h f l (Rohm li t) Ease of Installation and Maintenance (can be done by electrical contractor instead of specialized workers).

Ultra-compact DOPITM LED sealed Ult t l d module is coupled to an active SIDE face of a flexible light fiber and reduce light losses in a long fiber; enables to inject orders of magnitude higher flux and produce continuous monofilament large core fiber of any required length and luminance without any loss of power efficiency.

Expensive Robust b lk E i with an E i R b t bulky Engine ith optical concentrator coupled to a fiber's end aperture. Not suitable for low power SMD LEDs, since fiber's diameter should be prohibitively large to accept higher flux required for longer fibers. With HID sources such conventional coupling scheme causes significant flux losses, up to 75% for the best (and expensive) relatively long fibers in practical systems, which exponentially rise with fiber's length No integral Cladding. Outer j g g jacket should be used with associated extra cost as well as maintenance and installation problems.

Monolithic Core-Cladding g Monofilament large Core Fiber similar to classic telecom optical fiber. Integral thin cladding ensures environmental and UV protection, substituting a need for an additional outer jacket. Enables better luminance control and higher collimation of extracted flux.
